KTA Thermistor & RTD Sensor

Brand: Kele

The Kele KTA Series All-Purpose Thermistor and RTD Sensors provide remote temperature sensing for building automation systems and mechanical equipment room instrumentation. 

The active sensing element is made of a highly stable thermistor material or platinum RTDs. 

The KTA Series sensors are rugged, point-sensitive waterproof sensors featuring a 9" (22.8 cm) 304 stainless steel probe and brass fitting. 

The brass fitting has a 1/2" NPT male thread. 

The sensors are supplied with two 1/2" locknuts for easy installation in handy boxes (or other enclosures with 1/2" knockouts).
Features
  • Wide selection of thermistor and RTD curves
  • Tip sensitive for precise temperature response
  • All metal construction with 304 stainless steel probes
  • Easy to mount to duct, wall, or back box
  • Waterproof probe
